CAR-TRUCK SIDE FRAME.

SPECIFICATION forming part of Letters latent No. 620,911, dated March14, 1899.

Application filed November 9, 1896. Serial No. 611,545. (No model.)

To all whom it may concern:

Be it known that I, EDWARD F. GOLTRA, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Car- Truck Side Frames; andI do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

In the present invention I provide for the ready removal of theaxle-boxes and connect the transom channel-beams directly to the innerside of the journal-bar, which in such case I preferably form of greaterdepth in its middle than at its ends, and I preferably furtherstrengthen and support the structure by carrying the tie-bar upward andjoining its middle portion to the lower flange 0f the journal-bar. g

In the drawings, Figure 1 represents in side elevation a car-truck sideframe embodying my invention. Fig. '2 represents a top plan Fig. 3represents a section on the line 3 3 of Fig. 2 with the side bearingremoved; and Fig. 4 represents a modification, partly in plan and partly1 in section.

Similar letters of reference indicate similar parts throughout theseveral Views.

Referring to the drawings, B indicates the vjournal-bar, which ispreferably a single integral casting flanged above and below, as shown,and of greater depth at its middle than at its ends, so as not only toafford a sufficient bearing for the transom channelbeams, but toconstitute in itself an arch-bar.

The journal-bar B, as shown in Figs. 1, 2, and 3, may have integralplate-like projections or cheek-pieces b, to which the transomchannel-beams I are secured by rivets or the like passing through thewebs of the beams,

and below the nuts, as shown.

F indicates a tie-bar which may directly connect the pedestals orguide-columns D D for the axle-boxes E, as indicated in dotted lines inFig. 1, but which is preferably arched at its middle portion, as shownin full lines in said figure, and riveted to the lower flange of thejournal-bar, thereby tying the pedestals to the journal-bar as well asto each other. The axle-box springs M are interposed in the usual mannerbetween the axle-boxes E and the journal-bar and areadapted to be madeadjustable.

The pedestals D D extend between the jour nal-bar and tie-bar and areheld in place by bolts G, which pass through the hollow interior of thepedestals and are secured above It is evident that an axle-box can bequickly removed by removing the corresponding outer bolt Gand slippingthe outer pedestal out from between the journal-bar and tie-bar, therebypermitting the like lateral removal of the axle-box and Withoutdisconnecting any other portionsv of the structure.

Having thus described my invention, what I claim is 1. In a car-truckside frame, the combination of a journal-bar deeper at its middle thanat the ends, a transom secured to said deeper'portion, a tie-bar archedat its middle and secured to the deeper portion of the journal-bar,pedestals secured between the ends of the journal-bar and thedownwardly-extending ends of the tie-bar, vertically-movable axle-boxesguided between the pedestals, and springs reacting between the ends ofthe journal-bar and the boxes.

2. In a car-truck side frame, a journal-bar, a transom connected to theinner side of the j ourn al-bar, a tie-bar,said tie-bar being arched atits middle portion and attached thereat to the lower flange of thejournal-bar pedestals between the tie-bar and journal-bar, verti=cally-movable axle-boxes guided between the 3. In a car-truck sideframe, the combination of a journal-bar, tie-bar, transom-beams,

pedestals secured between the ends of the journal-bar and those of thetie-bar, axleboxes movable vertically between the pedestale, and springsreacting between the ends of the journal-bar and the boxes, thejournal-bar havinglateral flanges at its upper and lower edges betweenwhich the transom-beams are secured, and being flattened and widened outat its ends between the pedestals to form seats for the box-springs.

4. In a car-truck side frame, the combination of a journal-bar, tie-bar,channel transom-beams, pedestals secured between the ends of thejournal-bar and those of the tiebar, axle-boxes movable Verticallybetween EDWARD F. GOLTRA.
